Application April 24, 1939, Serial No. 269,771

4 Claims.

The present invention relates to improvements in cylinder paper making machines of a type disclosed in Letters Patent No. 1,746,434, and has for its primary object to provide an improved deckle construction adapted to form a sharper and neater edge on the paper as the same is formed on the cylinder.

More specifically, the invention comprises a rotating disk having contact with the surface of the cylinder to form the marginal edge of the paper and providing means for adjusting the disk to vary the width of the paper in accordance with the adjustment made by the deckle.

A further object is to provide a device of this character of simple and practical construction, which is eflicient and reliable in performance, relatively inexpensive to manufacture and otherwise well adapted for the purposes for which the same is intended.

Other objects and advantages reside in the details of construction and operation as more fully hereinafter described and claimed, reference being had to the accompanying drawings forming part hereof, wherein like numerals refer to like parts throughout, and in which Figure 1 is a plan view of one of the deckles shown in operative position with respect to the cylinder.

Figure 2 is a sectional View taken substantially on a line 2-2 of Figure 1.

Figure 3 is a sectional view taken substantially on a line 33 of Figure 1.

Figure 4 is a sectional View taken substantially on a line 4-4 of Figure 2.

Figure 5 is a sectional View through the washer taken substantially on a line 55 of Figure 4.

Figure 6 is a fragmentary perspective view of the adjusting handle for the supporting rod of the disk.

Figure '7 is a transverse sectional view through the disk, and

Figure 8 is a perspective view of the supporting arm for the disk.

Referring now to the drawings in detail, wherein for the purpose of illustration I have disclosed a preferred embodiment of the invention, the numeral 5 designates one of the screen cylinder molds on which the paper is formed in a manner well-known in the art, and the numeral 6 designates the cylinder of the deckle which overlies one end of the cylinder 5 and to the outer end of the cylinder 6 is connected the water feed pipe I, the inner end of the cylinder bein closed.

A piston 8 has a Working fit in the barrel of the cylinder 6 and the inner portion of the cylinder is formed with a longitudinally extending slot 9 through which the water is sprayed onto the cylinder 5 to wash the undesired paper stock therefrom, the adjustment of the piston 8 in the cylinder 6 determining the Width of the paper being made on the machine.

The piston 8 is secured on the inner end of the piston rod l0 which i also provided with a conical collar I l against which is secured an edge washer l2 which is in the form of a laterally projecting finger projecting outwardly through the slot 9. To the outer end of the finger I2 is secured a channel-shaped extension l3, and as more clearly illustrated in Figure 5 of the drawings, the finger [2 at its side facing the adjacent end of the cylinder 5 is formed with a longitudinally extending, V-shaped groove M, the finger l2 and extension I3 cooperating to form a guide for directing the Water from the cylinder 6 laterally therefrom with a sharply defined edge for the film of water which is projected outwardly through the slot 9 onto the cylinder 5.

The rod l0 projects outwardly through the outerendof the cylinder 6 and is formed with a handle M. A plurality of guides [5 are also mounted on the cylinder 6 within which is slid ably inserted a rod I6, the outer end of the rod being formed with a laterally projecting handle l1, and the rod is secured for uniform reciprocating movement with the piston rod [0 by means of a set screw I 8 which is threaded through a guide l9 secured to the rod l0 adjacent the handle I4.

On the inner end of the rod [6 is a laterally extending arm 20 freely mounted thereon and secured in a fixed position on the rod by means of a pair of spaced collars 2|. A coiled spring 22 is also mounted on the rod I6 with one end engaging the arm 20 and its other end secured to one of the collars 2| to yieldably urge the arm in a direction toward the cylinder 5. The outer end of the arm 20 is formed with a plurality of longitudinally spaced openings 23 for adjustably receiving a bolt 24 on which is rotatably mounted a disk 25, the disk being formed of a pair of outer plates 26 and an intermediate plate 21, the outer plates being of greater diameter, as more clearly illustrated in Figure 7 of the drawings, whereby to receive between their outer edges a rubber ring 28 which is clamped between the plates 26 and with its outer edge projecting outwardly beyond said disks. The plates and ring forming the disk are held in assembled position by means of a flanged collar 29 on which is threaded a washer 3B.

As more clearly illustrated in Figure 1 of the drawings, the disk 25 'is secured in position in alignment with the guide washer l2 and the edge of the rubber ring 28 is adapted to contact the surface of the cylinder 5 whereby to form the edge of the paper on said cylinder.

Supported in the guide I5 is also a rod 3| on which is slidably mounted a cleaner 32 having an edge portion working in the slot 9.

The piston 8 is secured in adjusted position in the cylinder 6 by means of a set screw 33 threaded through the union 34 for engaging the piston rod l0.

Adjustment of the tension of the edge cutting disk 25 may be accomplished by releasing the wing nut l8 and rotating the rod IS in a desired direction in its supporting bearing or guide.

By reason of this construction it will be apparent that the deckle is capable of producing a sharper and cleaner edge for the paper as the same is formed on the cylinder 5. It will be understood that each end of the cylinder 5 is provided with one of the deckles constructed in accordance with the present invention.

It is believed the details of construction and manner of operation of the device will be readily understood from the foregoing without further detailed explanation.

Having thus described the invention, what I claim is:

1. In a deckle for paper making machines including a paper making cylinder, means for spraying a liquid against the cylinder to remove stock at the side margin of the sheet of paper formed on the cylinder, a pivotally mounted gage support, a gage rotatably mounted on the support for Working against the cylinder to define the edge of the sheet, and spring means engaging the support for urging the gage into cylinder contacting position.

2. In a deckle for paper making machines including a paper making cylinder, means for spraying a liquid against the cylinder to remove stock at the side margin of the sheet of paper formed on the cylinder, a rotatable sheet contacting gage, spring means yieldably urging the gage into engagement with the cylinder, and means for varying the pressure of the gage against the cylinder.

3. In a deckle for paper making machines including a paper making cylinder, a cylindrical spray pipe having a longitudinal slot adapted to spray a liquid against the cylinder to remove stock at the side margin of the sheet of paper formed on the cylinder, means adjustably mounted in the pipe to vary the effective Width of the spray, a guide carried by the spray adjusting means and projecting laterally through said slot, a manipulating handle for said spray adjusting means, a rod slidably and rotatably carried by the pipe, a lateral arm pivoted on the rod, a sheet contacting gage rotatably mounted on the arm, spring means yieldably urging the gage into engagement with the cylinder in alignment with said guide, and means connecting the handle and the rod for simultaneous adjustment of the spray adjustment means and the gage to vary the width of the paper.

4. In a deckle for paper making machines including a paper making cylinder, a spray pipe having a longitudinal slot adapted to spray a liquid against the cylinder to remove stock at the side margin of the sheet of paper formed on the cylinder, a spray guide projecting laterally through the slot, means positioned in the pipe and operable outwardly thereof for adjusting the guide to regulate the effective width of the spray, a rod rotatably and reciprocably mounted on the pipe, an arm pivoted on the rod and projecting radially therefrom, a gage rotatably mounted on the outer end of the arm and supported in contacting engagement with the cylinder, and means connecting the rod to the guide adjusting means for simultaneous movement therewith.
